Spooling Space

Spooling space is the amount of disk space
that is used to store and process requests in the print queue. Spooling space
is the single most important factor to consider when deciding which systems
to designate as print servers. When users submit files for printing, the files
are stored in the /var/spool/lp directory until the files
are printed. The size of the /var directory depends on
the size of the disk and how the disk is partitioned. Spooling space can be
allocated in the /var directory on the print server,
or mounted from a file server and accessed over the network.

Note –

If /var is
not created as a separate file system, the /var directory
uses space in the root (/) file system. The root (/) file system is likely to be insufficient on a print server.
